摘　　要：Gemini型表面活性剂的结构和性质与传统的表面活性剂有很大的不同,例如Gemini型表面活性剂可以视为两个普通表面活性剂在亲水基或者靠近亲水基处由连接基团通过化学键连接而成;Gemini表面活性剂的C20值和cmc值都比传统表面活性剂的值要低很多。着重介绍了Gemini型表面活性剂的特性,结构与表面活性的关系以及应用。Gemini surfactants are vastly diferent from the conveniont suefactants in structure and function. For example ：Gemini surfactants can be regared as the structure that two common surfactants are connected in the two hydrophilic groups or near the groups by spacer through bond ; the values of and CMC of Gemini surfactant are lower than the values of the ordinary surfactants. Gemini particular structure, unique characteristics, surfact cativities and uses were introduced.
